Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air filters, in particular to an automobile air filter. BACKGROUND

[0002] The air filter is an important component in the automobile engine, and its main function is to filter out most of the dirt in the air to reduce the early wear of the cylinder, piston, piston ring, valve and valve seat. The air filter is usually located at the inlet of the air inlet, and when the automobile is running, the dirt in the air will be filtered out by the air filter element to ensure sufficient engine air intake.

[0003] At present, during the use of the air filter, if the paper filter element absorbs too much dirt, the air intake of the filter element will be reduced, thereby affecting the power of the engine. In view of the above technical problems, the applicant has searched some prior art to solve the above problems, for example, a multi-stage high-precision self-cleaning air filter with patent number CN117052574B, which mainly uses the technical means of monitoring the gas pressure difference on both sides of the filter element body to judge the blockage degree of the surface of the filter element body, and starting the cleaning mechanism to clean it when it needs to be cleaned, avoiding the traditional fixed time start, causing the filter element body to be over-washed, accelerating the aging of the filter element body, and the cleaning mechanism quickly cleans the surface of the filter element body, reducing the air intake resistance of the filter element body. Through the analysis of the applicant, the disadvantages of the technical scheme are: the above-mentioned cleaning mechanism only cleans the filter element when the filter element is seriously blocked, if the air humidity is large, the filter element can filter out the dirt and water in the air with large humidity, and the mixture of these dirt and water is easy to block and adhere to the surface of the filter element, which makes it difficult to clean the blocked dirt, thereby reducing the service life of the filter element. SUMMARY

[0010] A collecting box is installed at the bottom of the annular shell, and a plurality of water inlet holes are provided at corresponding positions of the bottom of the annular shell.

[0011] As a preferred embodiment of the above technical solution, a transmission assembly is installed between the circular plate and the filter cartridge, and the transmission assembly includes an outer gear ring. One end of the circular plate extends through the circular shell, and an outer gear ring is provided on the inner wall of this end of the circular plate. A gear is rotatably installed on the end face of this side of the circular shell, and the gear and the outer gear ring are engaged with each other. An inner gear ring is provided on the periphery of the filter cartridge, and the inner gear ring is engaged with the gear.

[0012] As a preferred embodiment of the above technical solution, a vibration assembly is installed under the filter cartridge, and the vibration assembly includes a connecting plate, one end of the connecting plate is connected to a spray assembly, and the spray assembly is connected to a collection box. A movable plate is installed on the top of the connecting plate, and the movable plate is located under the filter cartridge, and the movable plate extends into the gap of the filter paper on the filter cartridge.

[0013] As a preferred embodiment of the above technical solution, the connection between the movable plate and the connecting plate is a rotational connection, and a plurality of elastic members are installed between the movable plate and the connecting plate.

[0014] As a preferred embodiment of the above technical solution, the spray assembly includes a water pipe, and a water pipe is connected to one side of the collection box. The water pipe is in a multi-section bend shape, and the part of the water pipe located below the filter cartridge is a horizontal section. Several spray heads are installed on the periphery of the water pipe, and the spray heads are all facing vertically downward.

[0015] As a preferred embodiment of the above technical solution, the water pipe is connected to a connecting cylinder near the vibration component, and a plurality of push rods are slidably installed on one side of the movable plate near the connecting cylinder. A piston is provided at the other end of the push rods, and the piston is movably installed in the connecting cylinder.

[0016] As a preferred embodiment of the above technical solution, a filter is installed in the collection box, and the filter is located above the connection position between the water pipe and the collection box.

[0017] As a preferred embodiment of the above technical solution, a guide plate is provided on the inner wall of the shell, the guide plate is inclined and faces the vibration component, and a storage box is installed at the bottom of the shell.

[0018] The beneficial effects of the present invention are:

[0019] 1. In the present invention, air enters the annular shell through the first intake pipe. Since the first intake pipe is tangent to the outer wall of the annular shell, the air entering the annular shell flows along the inner wall of the annular shell. Under the action of centrifugal force, dirt and moisture in the air are closer to the inner wall of the annular shell, so that the air can be preliminarily separated from the dirt and moisture. The air entering the annular shell will also impact the blades, so that the blades drive the annular plates to rotate, which can guide the air flow. When the air impacts the blades, it will contact the condensing plate, and the air will exchange heat with the condensing plate, so that the water vapor in the air condenses into water droplets attached to the condensing plate, thereby reducing the air humidity. The air enters the outer shell through the second intake pipe. The humidity of the air filtered by the filter cartridge at this time is relatively low. Therefore, it is not easy for moisture to adhere to the filter cartridge, thereby effectively preventing dirt and moisture from mixing to form lumps attached to the surface of the filter cartridge, thereby effectively preventing the service life of the filter cartridge from being reduced.

[0020] 2. In the present invention, the annular plate rotates under the drive of a plurality of blades. Through the cooperation of the outer gear ring, the gear and the inner gear ring, the annular plate drives the filter cartridge to rotate. After the filter cartridge rotates, the dirt filtered in the gaps between the filter papers on the filter cartridge is thrown off the filter paper due to centrifugal force and its own gravity, thereby ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge, and effectively preventing the service life of the filter cartridge from being reduced.

[0021] 3. In the present invention, when the filter cartridge rotates, the filter paper on the filter cartridge will contact the movable plate. During the process of the filter paper contacting the movable plate and passing over the movable plate, the filter paper here will produce a shaking motion, which makes it easier for dirt attached to the gaps in the filter paper to fall off, thereby effectively preventing dirt from clogging the filter paper, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge, and effectively preventing the service life of the filter cartridge from being reduced;

[0022] 4. In the present invention, part of the air entering the annular shell will enter the collection box through a number of water inlet holes. When the amount of air in the collection box increases, the air will squeeze the water in the collection box, causing the water to enter the water pipe and finally be sprayed out from a number of sprinkler heads. The water sprayed from the sprinkler heads will cause the fallen dirt to settle, and at the same time, it will also adsorb the dirt in the air flowing under the several sprinkler heads, thereby reducing the amount of dirt floating in the shell, thereby reducing the situation where the dirt returns to the gap between the filter papers again, further effectively avoiding the blockage of the filter paper by the dirt, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge, and further effectively avoiding the reduction of the service life of the filter cartridge.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figure 1-Figure 7 As shown, an automobile air filter comprises a housing 1 and a filter cartridge 2, and the air filter further comprises:

[0034] The annular shell 3 is installed at the inner end of the shell 1. The air outlet pipe 13 on the shell 1 is connected to the hollow position in the middle of the annular shell 3. One end of the filter cartridge 2 is sleeved in the hollow position in the middle of the annular shell 3, and the other end is rotatably installed at the other end of the inner cavity of the shell 1.

[0035] The annular plate 4 is rotatably mounted in the annular shell 3. A plurality of blades 41 are arranged on the periphery of the annular plate 4. Condensation plates 42 are installed on both sides of the blades 41.

[0036] The annular shell 3 is connected to the air inlet pipe 11 and the air inlet pipe 2 12. The air inlet pipe 11 is arranged longitudinally and perpendicular to the axis of the annular shell 3. The air inlet pipe 11 is tangent to the outer wall of the annular shell 3. The other end of the air inlet pipe 11 extends out of the outer shell 1. One end of the air inlet pipe 2 12 is also tangent to the outer wall of the annular shell 3. The other end of the air inlet pipe 2 12 is spirally curved.

[0037] A collecting box 6 is installed at the bottom of the annular shell 3 , and a plurality of water inlet holes 31 are provided at corresponding positions on the bottom of the annular shell 3 .

[0038] In one case of this embodiment, the condensing plate 42 can be energized indirectly by energizing the annular plate 4 , and the condensing plate 42 can be a semiconductor refrigeration plate.

[0039] The air in the filter cartridge 2 is then blown away by the air inlet pipe 11 and the air inlet pipe 12 is blown away by the air inlet pipe 11. The air in the filter cartridge 2 is then blown away by the air inlet pipe 11 and the air inlet pipe 12 is blown away by the air inlet pipe 11. The air in the filter cartridge 2 is then blown away by the air inlet pipe 11 and the air inlet pipe 12 is blown away by the air inlet pipe 11.

[0040] After the air enters the annular shell 3, it is guided by the blades 41 so that it flows around the inner wall of the annular shell 3 before being discharged into the outer shell 1 through the second air inlet pipe 12. This allows the air to come into contact with the multiple condensing blades 42, thereby condensing the water vapor in the air into water droplets as much as possible, further reducing the air humidity, thereby effectively preventing dirt and water from mixing to form lumps and adhering to the surface of the filter cartridge, thereby further effectively preventing the filter cartridge from being shortened in service life.

[0041] After the air enters the annular shell 3, the rotation of the blades 41 can accelerate the air to be discharged from the air inlet pipe 2 12, thereby reducing the contact time between the air and the water droplets, thereby further reducing the humidity of the air entering the shell 1, thereby effectively preventing the dirt and water from mixing to form lumps and adhering to the surface of the filter cartridge, further effectively preventing the service life of the filter cartridge from being reduced;

[0042] The water droplets attached to the condensing sheet 42 are thrown onto the inner wall of the annular shell 3 under the rotation of the blades 41, and slide down along the inner wall of the annular shell 3 through a number of water inlet holes 31 and flow into the collection box 6, thereby effectively preventing the air from coming into contact with the water droplets again and increasing the air humidity; when the water droplets are thrown toward the inner wall of the annular shell 3, the water droplets will come into contact with the dirt in the air, and these dirt will adhere to the water droplets and flow into the collection box 6 along with the water droplets, which can reduce the dirt content of the air entering the outer shell 1, thereby reducing the burden on the filter cartridge 2, and further effectively avoiding the reduction of the service life of the filter cartridge.

[0043] Furthermore, a transmission assembly 5 is installed between the annular plate 4 and the filter cartridge 2. The transmission assembly 5 includes an outer gear ring 51. One end of the annular plate 4 extends through the annular shell 3. The outer gear ring 51 is provided on the inner wall of this end of the annular plate 4. A gear 52 is rotatably installed on the end face of the annular shell 3. The gear 52 and the outer gear ring 51 are engaged with each other. An inner gear ring 53 is provided on the periphery of the filter cartridge 2. The inner gear ring 53 and the gear 52 are engaged with each other.

[0044] In actual application of this embodiment, the annular plate 4 rotates under the drive of the plurality of blades 41. Through the cooperation of the outer gear ring 51, the gear 52 and the inner gear ring 53, the annular plate 4 drives the filter cartridge 2 to rotate. After the filter cartridge 2 rotates, the dirt filtered in the gaps between the filter papers on the filter cartridge 2 can be thrown off the filter paper due to the centrifugal force and its own gravity, thereby ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and effectively preventing the service life of the filter cartridge from being reduced.

[0045] The rotation direction of the filter cartridge 2 is the same as the flow direction of the air discharged from the second air inlet pipe 12. In this way, when the dirt is thrown off the filter cartridge 2, the flowing air can blow the dirt, causing the dirt to hit the inner wall of the shell 1 and finally collect at the bottom of the inner cavity of the shell 1. This effectively prevents the dirt from being thrown off from returning to the filter paper, thereby further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively preventing the service life of the filter cartridge from being reduced.

[0046] When the filter cartridge 2 rotates, the flowing air is attracted to flow around the filter cartridge 2, and the air slowly approaches the filter cartridge 2 and passes through the filter cartridge 2, thereby accelerating the air filtration efficiency, thereby ensuring that the amount of air entering the engine is sufficient and ensuring the normal operation of the engine.

[0047] Further, the vibration assembly 8 is installed below the filter cartridge 2, the vibration assembly 8 comprises a connecting plate 81, one end of the connecting plate 81 is connected with the spraying assembly 7, the spraying assembly 7 is connected with the collecting box 6, the top of the connecting plate 81 is installed with a movable plate 82, the movable plate 82 is below the filter cartridge 2, and the movable plate 82 extends into the gap of the filter paper on the filter cartridge 2.

[0048] In actual application, when the filter cartridge 2 rotates, the filter paper on the filter cartridge 2 will contact the movable plate 82, and the filter paper will produce a shaking action in the process of contacting and passing the movable plate 82, so that the dirt attached to the filter paper gap is more easily dropped, thereby effectively avoiding the dirt from blocking the filter paper, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and effectively avoiding the service life of the filter cartridge from being reduced.

[0049] Further, the connecting portion between the movable plate 82 and the connecting plate 81 is a rotating connection, and a plurality of elastic members 83 are installed between the movable plate 82 and the connecting plate 81.

[0050] In actual application, after the filter paper contacts the movable plate 82, the filter paper will first press the movable plate 82, so that the elastic member 83 is compressed, and when the filter paper passes the movable plate 82, the movable plate 82 returns to the original position under the rebound force of the elastic member 83 and is in a shaking state, so that the movable plate 82 hits the filter paper rotating behind, so that the filter paper produces a shaking action after a hitting action, and all positions of the filter paper will produce the above-mentioned action when the filter cartridge 2 rotates, thereby enhancing the effect of dirt falling from the filter paper gap, further effectively avoiding the dirt from blocking the filter paper, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively avoiding the service life of the filter cartridge from being reduced.

[0051] The movable plate 82 will hit the dirt falling down in the rebound process, so that the falling dirt quickly moves away from the filter cartridge 2, avoiding the dirt from returning to the filter paper, thereby further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively avoiding the service life of the filter cartridge from being reduced.

[0052] Further, the spraying assembly 7 comprises a water conveying pipe 71, one side of the collecting box 6 is connected with the water conveying pipe 71, the water conveying pipe 71 is in a multi-bent shape, the part of the water conveying pipe 71 below the filter cartridge 2 is a horizontal section, a plurality of spraying heads 72 are installed on the periphery of the water conveying pipe 71, and the spraying heads 72 are vertically downward.

[0053] In actual application of this embodiment, part of the air entering the annular shell 3 will enter the collection box 6 through the plurality of water inlet holes 31. When the amount of air in the collection box 6 increases, the air will squeeze the water in the collection box 6, causing the water to enter the water pipe 71 and finally be sprayed out from the plurality of spray heads 72. The water sprayed from the spray heads 72 will cause the fallen dirt to settle, and at the same time, it will also absorb the dirt in the air flowing below the plurality of spray heads 72, thereby reducing the amount of dirt floating in the shell 1, thereby reducing the situation where the dirt returns to the gap between the filter papers again, further effectively avoiding the blockage of the filter paper by the dirt, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively avoiding the reduction of the service life of the filter cartridge;

[0054] Although the air will come into contact with water when passing under the several spray heads 72, thereby increasing the humidity of the air, the air at this time will soon pass through the filter cartridge 2, and the dirt in the gaps between the filter papers of the filter cartridge 2 here has been cleaned, which effectively prevents dust and water from mixing and agglomerating to block the filter cartridge 2.

[0055] Furthermore, the water pipe 71 is connected to a connecting tube 73 near the vibration component 8, and a plurality of push rods 84 are slidably installed on one side of the movable plate 82 near the connecting tube 73. A piston 841 is provided at the other end of the plurality of push rods 84, and the piston 841 is movably installed in the connecting tube 73.

[0056] In one aspect of this embodiment, a one-way valve is installed on the spray head 72 so that water can only be sprayed out from the spray head 72 .

[0057] When the filter element 72 is in the closed position, the filter element 72 is in the closed position, and the filter element 72 is in the closed position, so that the filter element 72 is in the closed position and the filter element 72 is in the closed position.

[0058] Furthermore, a filter screen 61 is installed in the collection box 6 , and the filter screen 61 is located above the connection position between the water pipe 71 and the collection box 6 .

[0059] In actual application of this embodiment, water, dirt and air entering the collection box 6 from the water inlet 31 are all filtered through the filter screen 61, thereby ensuring that the sprinkler head 72 is not easily blocked. At the same time, the air entering the housing 1 through the water pipe 71 is filtered, thereby further reducing the situation where dirt returns to the gap between the filter papers again, further effectively avoiding dirt clogging the filter paper, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively avoiding the reduction of the service life of the filter cartridge.

[0060] Furthermore, a guide plate 9 is provided on the inner wall of the housing 1 , the guide plate 9 is tilted and faces the vibration assembly 8 , and a storage box 10 is installed at the bottom of the housing 1 .

[0061] In actual application, this embodiment ensures that the air flows to the bottom of the plurality of sprinkler heads 72 through the guidance of the guide plate 9 and the movable plate 82, so that the dirt in the air is adsorbed by the water, thereby further reducing the situation where the dirt returns to the gap between the filter papers again, further effectively avoiding the clogging of the filter paper by the dirt, further ensuring the air permeability of the filter paper, improving the filtering effect of the filter cartridge 2, and further effectively avoiding the reduction of the service life of the filter cartridge; the water and dirt are finally collected in the storage box 10, and the storage box 10 can be cleaned regularly.
